Hello Ovanes, Thanks for your reply. You means like this? catch ( const fs::basic_filesystem_errorfs::path& e ) { // transform e.what() to a new string by search and replace // rethrow an exception } That would be ok for this single case. But who knows if there's other similar cases that need this similar hand-written code processing? I want to depress the similar message in a uniform way.

Hi! what about catching the exception and rethrowing your own one? Greetings, Ovanes
